To all it may concern.

Beitlmown that I, Anvm F. HARRISON, a

citizen-"of the United States,- residin at gme.

4 Heretofore it has been. found difilcult to start the engine of an automobile, in cold weather, especially after the automobile has stood for any length of time in the cold. .In other words, that after considerable cranking of the engine shaft it has been found arduous to make the carbureter respond sufliciently by the suction in'the ,en-

'gine, to supply fuel to the engine. This difiiculty is experienced 'eons'ide 'ably in coldweather.

The principal object of the inventionistoprovide means to overcome this difiiculty, and to accomplish this purpose this means is arranged that, a supplyof already formed gas may be introduced into the engine cylin- 'ders independent of the carbureter.

One of the features of the invention is to provide a connection between the carbureter and the cylinder, through which the supply of already formed gas is introduced, which connection not only connects the carbureter with the cylinders, but also constitutes a reservoir to hold the already formed gas.

Another feature of the invention is the provision of means for introducing already formed gas, mixed with air through the air intake channel of the carbureter.

The invention comprises further features and combination of parts, as hereinafter set forth, shown in the drawings and claimed.

In the drawings: Figure 1 is a diagrammatic view showing the application of the starting device to the engine of an automobile. Fig. 2 is a sectional view of the connection between the'source of supply of already formed gas and the connection between the engine cylinders and the carbureter. Fig. 3 is a plan view of Fig. 1. Fi 4 is a detail sectional view of the va ve 24.

"not, be in vain, for the engine will hesup- Referring to-the drawings 1 designates the automobile, while 2 denotes the front dash, whereas 3 designates the engine cylinders, which are of the usual construction. The usual form of carburetor 4 is provided, between which and the cylinders a'tubular connection 5 is arranged. The portion 5" of the tubular connection constitutes areservoir,*-in which already formed gas may be stored, while'the automobile is standing for considerable length of time in the cold, so that, when the c'haufi'eur returns to his machine and 'desires to crank his engine, it will 0 plied with fuel, such as alreadyformed gas 7 from the reservoir between the carburetor and the cylinders; After the engine has been'started thewsuction therein is considerably greater, which will cause the carburetor to finally, respond, so as to introduce the carbureter fuel. After the carbureter has responded, the supply of already formed gas is cut on, This connection (which constitutes. a reservoir for such already formed 30 gas) is one of the principal features of the invention.

Anacetylene gas generator 6 is provided,

which is only one method of providing already formed gas, for it is to be rememberedthat such gas may be obtained from; any suitable source of supply whatsoever.

Extending from the connection 5 in :1 lateral direction is a tube or pipe 7. Extend ing telescopically into the tube or pipe 7 is one arm 8' of'the angular pipe'or tube 9, which arm 8 isheld in position by the set screws 10. The'angular pipe or tube 9 is provided with cutoff valve 11, so as to control the supply of already formed gas from the supply or generator 6. Extending into the arm 12 of the angular pipe or tube 9 is one portion 13 of the angular tube 14, into the portion 15 of which the pipe 16 extends. The portion 13 of the pipe or tube 14, andthe pipe 16 are held in position by the set screws 17 and 18. The pipe 16 connects to the supply or generator 6.

The pipes 7, 7 20 are joined by a valve 24, at the junction 19. By manipulating this valve already formed gas may pass through the pipe 7 or through the pipes 20 p and 21, through the carbureter,'then to the cylinders in the usual way. The pipes 20 and 21 are telescopically joined, and held in 110. the desiredpositions by the screw 22.

'In starting the cut oil valve 11 is opened,

, pipes 20 and 21, until the reservoir is permitting the already formed gas, from any i suitable source, such as the generator, to pass into 5, and subsequently into the reservoir 5, either by way of the pipe 7 or the filled. Then the crank shaft (not shown) is turned in the usual way to start the engine, and in so doing, the gas from the reservoir 5 is drawn into the cylinders, which causes the explosion, which in turn starts the engine. If it is desired to direct the already formed gas through the pipes 20 and 21, the valve 24 is manipulated so as to assume the position shown in dotted lines in Fig. 4, which will prevent it from passing through the pipe 7. Then by cranking-the engine shaft (not shown), the already formed gas including some air is drawn directly through the carbureter, as in the usual way, to the reservoir 5 If the valve 24 is arranged as shown in full lines in Fig. 4, the already formed gas will pass through the pipe 7 and not through the pipes 20 and 21. In thisinanner the already formed gas enters the reservoir 5 independently of the carburi ar. After the engine has become thoroughly started, and the carburetor is 'responding on every stroke of the istons of thecylinders, the supply of alrea y formed gas or fuel is cut otf by closing the valve 11.

In the drawings there is disclosed only one form of the invention, but in practical fields this form may require alterations, to which the applicant is entitled, provided the alterations are comprehended within the;

already formed gas from any source is,

adapted to be fed, a pipe connection between the lateral extension and the carbureter, and a valve located at the junction of this last named pipe and the lateral extension whereby the gas may be directed into the reservoir by way of the lateral extension and independently of the carbureter, or through the carburetor by way of the last named pipe.

In testimony whereof I have signedmy name to this specification in the presence of two subscribing witnesses.
